FLEXIBLE SHAFT-COUPLING.

Specication of Letters Patent,

Patented May ie, 1916.

Original application led December 8, 1914, Serial No.A 876,017. Divided and this application led July 1;

' 1915. Serial No. 37,439.

To all whom it may concern Be it known thatwe, WILLIAM P. B.

HAMILTON, residing at No. 54 Magnolia.vv

avenue, Jersey City, State of New Jersey, and HENRY VoeLEsoNe, residing at No. 578 Newark avenue, in said city and State, both citizens of the United States, have invented a new and useful Improvement in Flexible Shaft-Couplings, of which the following is a specification.

One object of our invention is to provide a means for detachably coupling the driveing end of one shaft with the driven end'of another shaft, and at the same time insulating the one from the, other, even though the shafts be running at. high speed and the coupling be subjectedv to a maximum of stress. v

This application is a division of ourap plication for patent for flexible shaft couplings, Serial No. 87 6,017 filed December e, i914. f

Another object of our invention is to provide a detachable insulating shaft coupling which Will be adaptable for high speed or a maximum of' stress and which will be inoperative connection although the axes of the coupled shaftsvary in a slight degree when in operation, and which will'be sub-` liect to a minimum of wear on the connecting parts and require little or no lubrication.

In the accompanying drawings,- Figure l' shows a side elevation of our device assembled, in perspective; Fig. 2 is a central hori.

aontal section of the device as shown in Fig. l; Fi 3 is a face view ofthe locking member o? our coupling; Fig. 4 is a perspective view of the locking member of our coupling; Fig. 5 is a cross-section view of the locking member of our coupling as shown in 3 and: and showing the method of rein forcing the material of the member.

Referring to the said drawings; on each of the shafts A and A2 is mounted a coupling member composed of collars Band B2 which form the hubs of the disks C and C. The collars B and B2 are fixed against rotation on the shafts A and A2 by means of key or other convenient means and they may be adjusted longitudinally on'the shafts A and A2- by means of binding screws a. The

Ag and g2 of proper width to engage the lugs e and e2 and to slide easily thereon, the said -slots or grooves being at right angles tof each other. The4 key disk F may be strengthened by rivets which will assist the material of the disk in resisting the 'stress produced when revolution of the shafts takes place. We prefer that, in this construction, Athe depthvof the said slots `be Somer' what less than'the height of the'lugs e so that when the parts are assembled in operative connection there will be a slight space between the opposing faces of the key disk and the coupling members with the result that the heads of the-rivets may be fiush with the surfaces of the key disk or even project to a 'slight extent above the surfaces of the key disk but yet will not come in contact with the opposing faces of the coupling members. v

The foregoing described form of our dethe rivets may, however, be set below the surfaces 'of the key disk in. which eventthe height ofthe lugs e may be even with the depth of the Ygroove g, or even less and the surfaces of the key disk may be in Contact with the opposing faces of the coupling members. It will be seen that in this construction the maximum resisting power of the material which insulates the coupling members from one another is utilized, and that, although the axis of one shaft be out of alinement with theI axis of the other and even though the axis of the shafts intersect at a slight angle near the junction of the shafts, the coupling members are still insulated from one another and the coupling is still operative.

It will be seen that even though insulation is not desired or necessary, the device nevertheless possesses the advantage of having its bearing surfaces constructed of metal and fiber Working upon each other, with a consequent great power of resistance to wear,

vice is best shown in Fig. 1. The heads of lack of necessity for lubrication and a minin mum of noise and vibration. l

We claim as our invention: y

l. In a shaft coupling, two oouplingmembers, each member consisting of a disk'provided with a hub, said disk being provided with a diemetrical lug, a key disk of ber strengthened by rivets, each face of seid disk being provided with a diametrical groove said grooves being at right angles to each other and of proper width to engage said lugs and of a depth less than the height of said lugs.

2. In a shaft coupling, two coupling members, each member consisting of ajdisk pro vided withv a hub, said disk being provided with 'a diametrical lug, a key disk of ber strengthened by rivets the heads of' strengthened by rivetseach face of said disk being provided with a diametrical groove,

said groovesbeing at right angles to eachA other yend of a. proper lWidth to engage said lugs and of a depth lessthan the height of said lugs.y

4. In a shaft coupling, two coupling members, each of which isprovided with a lug passing through its axis, a, key disk of ber strengthened by rivets the heads of which 1re set beneath the surfaces of the faces of the disk, each face of said disk being provided with a diametrical groove, said grooves being at right angles to each other and of a proper width to engage said lugs.

'.5. In a shaft coupling,`two coupling rnernbers, each of which is provided with nlug passing through itsaXis, a key disk of reinforced ben'cach face of Vsaid disk being provided with a diametrical groove, said grooves being at right angles to each other and of a. proper Width to engage said lugs.
